To allwhom it may concern Be it known that 1, CHARLES E. TonRANcn,

a citizen of the United Statesiof America,

and resident of Holyoke, in: the county of -Hampden and State of Massachusetts, have invented certain new and useful Improve ments in Paper-Machines, of which the following is a full, clear, andeXact description. A

This invention relates to improvements in a device for cleaning the wire of a Fourdrin. ier paper machine, that is the woven-wire. endless apron on the upper course or run of which the pulp is carried in the course of fabrication ofthe web. These aprons after a while become more or less clogged and impaired by specks of dirt, pitch, pulp and othermatter so. that it is a matter of desirafor freeing it of the accumulations. thereon and thereinof the character above nentioned.

The object of this invention is to provide a device, for cleaning thewire apron of a Fourdrinier paper machine, of improved character and one which. may easily, and at pleasure, be so operatedthat thebrush or cleaning member may be carried up to contact against the under or working side of the lower course or runof the apron, and then after the work of cleaning thereby has been performed, to be as easily lowered away from its operative position. And another object of the invention is to provide an improved construction ofa roller brush which is especially applicable for employment in this wire apron cleaning device and which will not be affected in anydetrimental way by the water and moistureto .which it is subjected by reason of its coaction with the wire apron. I 1 i The invention is'described in conjunction with the accompanying drawings and is set forth in the claims. 7

In the drawings :F1gure 1 is a plan view ,of the device forcleaning the wire 0r endless'apron of a Fourdrinier machine.

Fig. 2 is a front elevation of the same. Fig. 3 is a front elevation showing the opposite end portions of the device on-a larger scale, Fig. 4 being a plan of one end portion'and Fig. 5 being an end elevationof the same.

Fig. 6' is a-diagrammatic view showingthe wire or endless apron and on which indication is made of a location relatively thereto from time to time to clean the apron roll for use in the device; Fig. 8 is a cross] sectional view of Fig.7..

' In the drawings, A represent. a pair of members adapted to :be supported in any suitable manner and positioned in opposi tion beneath the lowercourse aof the wire apron B,-each said member comprising an upstanding post Z) having rack teeth 01 *on its side. w C C representcollars fitted to slide vertically about said toothed-posts having aper tures f f through the sides thereofopposite said rack teeth and provided'with rearwardly extending journalprcjections g and with forwardly extending journal projectionsiz...

The cleaner for the wire, which may be constituted by a brush roll E; has end journals thereof mounted :in the opposed Specification of letters Patent. Patented Nay, 23 1915 Application filed'January 18, 1915. Serial no. 2,915.

pair of journal projections g gof the said I vertically slidable collar members C. U

A position-controlling shaft G is mounted in the other opposed pairiofjournal' extensions 72, h; and this shaft opposite each of the posts has pinions i affixed thereon: and extending through the apertures f and jmeshing with the rack teeth of'said posts; and. said shaft also has a ratchet wheel is affixed thereon with which coacts a pawl m which is carried by the vertically "slidable collar which is adjacent said ratchet wheel. The

shaft G has the crank handle a for rotatively turning it.

By assuming that the device has the brush thereof in the lowered-position below and clear from the under-running course ofthe Fourdrinier wire 'apronand it is desired to elevate the brush for its cleaning coaction with theapron, it is only'necessary to turn the crank handle for a part of a revolution whereby through the action of the'pinions the vertically slidable collar members will be ,caused to climb or become elevated relatively tothe posts 6 which serve as the guidesand bearings. The elevation of the parts is-to be such as to bring'the-brush roll to its proper operative action relatively to the wire, which under the power of the paper machine givingiits progression, induces-the rotary motion tothe brush for its cleaning action.

The pawlholds the device in theelevationto which it is most properly -adjusted during the time the device is in operation,

, but after the work in a given time shall have been accomplished, the pawl is manually thrown out of engagement with the ratchet wheel, and'the collar members and the parts carried thereby-are lowered so that for the most of the time and while not-necessary, the brush isdown and away from its working position, when, of course, there is an avoidance of abrasive action between the 7 brush and wire for unnecessarily wearing these equipments.

From the position inwhich the brush roll of thecleaner is used, for instance one indicated by- E*, or one indicatedby E in Fig. 6,:; the roll is wet most of the time, but

usually about once a weekthere is an opportunity, when the machine is not running, for c the roll to dry out. These brush rolls have sometimes been made with wooden staves or lags carrying or holding the brass wire or other bristles of the brush, such staves have been secured-by wood screwsupon a wooden central roll bodygorlcore. a

- The swelling and shrinking of the wooden staves and the wooden core have not only twisted the roll outof'true, but'have caused loosening of the wood screws so that the roll would more'or'lesslgo to pieces and the loosened screws would. seriously damage. the

wire-apron. Tojobviate these troubles, a'

construction ofroll to be embodied in this cleaning devicehas been-devised and practhe core and which, staves carry "the wire bristles u. .The stavesare securedto the core by machine screwsjzqthe heads of which are countersunk into the staves, and the shanks of which extend through said staves and -with screw thread engagements into holes therefor in the tubular metal core. 7 1

This construction of rollis one which has been found to be simple, practicable and inexpensive of construction, but as more especially important, has also proved most eflic'ient and satisfactory as the wire apron cleaning element of the device.

Icla1m: 1..,In a device for cleaning the wire apron of; a Fourdrinier :paper machine, in combination, a pair of members adaptedito be positioned opposition beneath the lower mental .form,

course of the wire apron, each said member comprising an upstandlng'post having teeth on its side, members vertically slidable rela-,

tively to said toothed posts, a wire apron cleaner supported by and between said mem bers, and a posltioncontrolhng device for,

and carried by, said slidable members, in cluding ashaft having gear wheel connec-, tions with saidtoothed posts and means for holding said shaft locked against accidental rotation. 1 a
